Is this diamond too expensive or not ?

 

[nat82]

I''m actually looking for a diamond with wider top.

What kind of proportions that I''ll need to aim for this ? (to get better spread?)

 

[nat82]

any1???

Hi nat,

The diamond looks good so far. Is this an AGS with zero light performance grade?

If you wanted a spreadier stone, you would look for one with a shallower depth. However, when you go "there", you go away from ideal cut, which I wouldn't recommend. Ideally, you want the best cut you can find, to produce the best performing stone. Bigger in this case, may not be better.

Doing a search on here, I got prices from $946-1120 US.

Any reason for that? I love the 55% table with those other measurements.

The spread is very good for its weight. If you went to a 58% table it would only increase spread to 5.37 and would reduce the crown height to under 15%, reducing its balance of fire. By the numbers I like it as-is.

John, do shallower stones not make for "spreadier" ones? I was under the impression they did. And I almoost mentioned a larger table, but I thought shallower depth would get one there faster.

Am i totally off?


About this question I mean.

 

[JohnQuixote]

No Ellen, in technical terms you're absolutely right.

Example:

A 0.50 ct stone at 57/40.6/34.5 (tn girdle) can be 60% depth and spread 5.18 mm
A 0.50 ct stone at 57/40.6/34.5 (stk girdle) can be 62% depth and spread 5.06 mm

The effect is exaggerated with larger stones.

A 2.00 ct stone at 57/40.6/34.5 (tn girdle) can be 60% depth and spread 8.25 mm
A 2.00 ct stone at 57/40.6/34.5 (stk girdle) can be 62% depth and spread 8.00 mm

So, with a half-carat stone you're talking about a difference of 0.12 mm (all things equal) versus 0.25 mm for two carats. If choosing between those identical options, if girdle thickness is the only difference, it makes sense to go slightly larger (unless tension-setting). However it's rare that such identical options present themselves conveniently.

I think you said it best before.

Bingo.

Interesting comparisons on small stone vs. larger with spread. I appreciate the info John, and confirmation that I wasn''t giving out an incorrect answer.

Thank you sir!

It''s ICE Ideal H&A Cut with AGS certificate.
I''m pretty sure it''s the same with AGS0 ACA? Let me check that with MDX

If it''s an AGS0 ACA, comparable price is around USD$1600++

The reason is because I don''t really like a diamond that sit too high on the ring

So, if this diamond is an AGS0 ACA it''s not too expensive?

Nothing to worry about nat. The difference between 60% and 62% depth (all else equal) at .56 carats is only something like 0.08 mm.
You would never see the height difference in a ring so you should feel great about those numbers.

You can do a search here to check comparable internet pricing.

Also, just to clarify: AGS0 is the "Ideal" grade from the American Gem Society. This is what you might focus on in pricing comparisons. ACA ('A Cut Above') is a branded hearts & arrows diamond sold by the company I work for.

No problem nat. Looking good. The IS should tell you a lot.

Comparable online price if it's an AGS-0 (which it appears to be) would be USD1300.

Add USD100 for international postage, 10% GST, customs handling fee and you're up around AUD1850.

Great deal, if it's an AGS-0. Are you sure the price quoted includes GST?

http://www.jamesallen.com/diamonds/G-VS2-Ideal-Cut-Round-Diamond-1101349.asp?b=16&a=12&c=77&cid=131

it's definitely better right?

No, I wouldn't say it's definitely better. They're both appropriately priced, only you can decide what's most important to you.

The JA stone however is definitely a safer buy sight-unseen, even if the high number of inclusions in the SI2 suggests it's eye-clean.

Before you spend too long deciding though, confirm their availability.

Hi
Sorry for the slow response, It’s been a while since I have visited Pricescope, Very busy time of the year for us. John Pollard from Whiteflash contacted us re your posting, Thanks John.

The stone is not at my branch, but I will see what I can organize today and get Rebeccca to send you the details.

Kind Regards
Johan

 

[nat82]

Thx John!

Johan. How long usually does it take to get the IS image?

 

[mdx]

Hi Nat82

I checked on our enquiry system today and can’t find any reference to your enquiry. Its possible we have it under the name of your partner and perhaps Nat is not short for Nataly.

Could it be your enquiry was at our one of our Canada Branches and not Australia?

Also this stone appears as sold on our system,

If you could perhaps just contact the customer service consultant you are dealing with and ask them to contact me,

I will do my utmost to assist

Kind Regards
Johan

 

[nat82]

Hi Johan.

It was under my partner''s name. (Budi).
Anyway. I''ve sent an email to Rebecca. She was the one who''s dealing with my partner.

If it''s sold. Then it''s too late for me

Anyway. Thanks for your assistance.

Cheers.
Nat.
